other places; and it consists in the novel con-` struction andcombination of the parts hereinafter fully described and claimed.

In the drawings, Figure l is a side view of the grip, partly in section.Fig. 2 is a plan View of the grip. Fig. 3 is an end View of the grip.

A is a frame provided with a longitudinal i slot or opening B at itsmiddle part.

C represents two grip-fingers pivoted in the slot of the frame upon pinsc and provided with curved and pointed ends c. V

D is a spring arranged between lugs d on the lower parts of thegrip-fingers and normally holding them in their raised positions andresting against stops d on the frame.

The grip-lingers are arranged in inclined positions with their curvedand pointed ends facing toward each other.

E is a portion of the bottom of a car which runs upon car-rails in theordinary manner, and e is a portion of one of the car-axles.

F is a bracket which straddles the car-axle and which is provided withtwo projecting catchesf at its lower end for engaging with the curvedand pointed ends of the grip-iingers. Bolts f are provided for securingthe bracket to the bottom of the car. The bracket is arranged tostraddle the car-axle, because the car-axle is always ata fixed distanceabove the car-rails, and the catches are therefore secured in the properposition for engaging with the grip-fingers to the best advantage.

Gr represents lugs which project laterally from the middle part of theframe A, and g represents guide-sheaves which are journaled on pins g,carried by the said lugs and arranged vertically. The guide-sheavesengage with a central guide-rail H, which is secured between theordinarycar-rails and which keeps the grip mechanism in the mostdesirable position.

`I represents lugs at the `ends of the frame A, and J representsclevises pivoted to the said lugs by vertical pins z'. K represents barswhich are journaled in the said clevises in a horizontal position andprovided with sockets at their ends.

N represents the cables by means of which the cars are drawn along.These cables are arranged in pairs and are connected to the sockets k inany approved manner. Wire cables are preferably used; but the cables maybe of any other flexible material, such as rope, or chains may be used.The pins z' permit the grip mechanism to pass around curves and bends,and the pivotal connection of the bars permits the grip mechanism toadapt itself to changes in the grade.

The car is engaged automatically by pressing down one of thegrip-fingers. The rear grip-finger in the direction of motion draws thecar along level rails and up inclines, and the front grip-fingerregulates the descent of the car upon down grades.

What I claim isw l. The combination, with a cable grip frame, and a pairof grip-iingers pivoted to the frame and provided with curved andpointed ends; of a car provided with an axle, and a bracket whichstraddles the said axle and which is provided with catches for engagingwith the said grip-iingers.

2. The combination, with a cable grip frame, and a grip-finger pivotedto the frame and provided with a curved and pointed end, saidgrip-finger being normally held in an inclined position; of a carprovided with an axle, and a bracket which straddles the said axle andwhich is provided with a catch for engaging with the said grip-finger.

3. The combination, with a cable-grip frame provided with a longitudinalslot, of a pair of grip-'fingers arranged in the said slot and pivotedto the said frame, asingle spring arranged between the lower parts ofthe said grip-fingers, and a car provided with a bracket hav- IOO guidearranged under the said frame and engaging with the said sheaves,elevises pivoted by vertical pins to the end portions of the said frame,pairs of sockets provided With coupling-hars Which are journaledhorizon-A tally in the said clevises, and pairs of cables connected tothe said Sockets.

In testimony whereof 1 have aiixed my signature in the presence of twoWitnesses.
